Practice Case study p. 224 part: Tuberculosis (TB) in indigenous populations. Lily was a recent science graduate of the University of Alberta and was 11 months into her 12 - month Master of Science in Global Health degree, at Dalhousie University. This relatively new program was created to provide the multidisciplinary training required of scientists working to meet the complex challenges of global public health issues. The University had partnered with the National Collaborating Centre for Indigenous Health (NCCIH) and that was why Lily now found herself doing her Global Health Field Practicum in the Northern Territories, working on a study of drug resistant TB infections among Innuit communities. The different communities included in her research were close to 7000 individuals, with multiple diagnosed cases of TB. And while she was grateful that drug-resistant TB in Canada remained below the global average (Public Health Agency of Canada, 2019), she was cognizant of the possibility…
The most selectively toxic antibacterial agents are those that interfere with bacterial cell wall synthesis. This is because ________. Group of answer choices bacterial cell wall synthesis is easily inhibited whereas eukaryotic cell wall synthesis is more resistant to the actions of the drugs bacterial cell walls have a unique structure not found in eukaryotic host cells eukaryotic cells do not take up the drugs eukaryotic cells inactivate the drugs before they can do any damage

Describe and explain the difference in results if the serial dilution step of the T4 bacteriophage suspension inour experiment was skipped (i.e., all of Step #3 of the procedures was skipped)? _________________________Current EventsThe Johnson and Johnson COVID-19 vaccine consists of inactivated adenovirus that has been altered to containgenetic information encoding SARS-CoV-2 surface spike proteins. The virus targets and delivers this geneticinformation to the cells of our respiratory tract, which produce benign SARS-CoV-2 surface spike proteins butare effective for training our immune system to defend us against SARS-CoV-2.Based on this information and your knowledge of viruses in general, could T4 bacteriophage be used in place of
Question 1 Why have the majority of viruses evolved to bind to a host surface receptor that serves an essential function in the host cell? This is completely accidental. These host receptors are poorly protected by the adaptive immune system, making them an easy target for the virus. O Because proteins that perform essential functions are located only on the surface of the host cell. O Host surface receptors that are essential for the host will always be expressed and present on the host.
Answer the following 1.Are viruses living or non-living organisms? 2. What is the difference between HIV and AIDS? 3. HIV is classified as a retrovirus. What are retroviruses? 4. In your own words, provide a short summary of the HIV replication cycle. 5. Why is reverse transcriptase an important enzyme in the replication cycle of HIV? 6. In the chapter about enzymes, we have discussed how drugs are basically inhibitors. There are currently a multitude of Antiretroviral therapy (ART or ARV) options available to people living with HIV (PLHIV) so that the viral replication is suppressed and does not progress to AIDS. What do you think these drugs target? Discuss briefly. 7. SARS-CoV-2, the virus that causes CoVid-19, belongs to the Coronaviridae family. Viruses under this family have a genome made of single-stranded positive-sense RNA. Is this similar to the viral genome of HIV? If so, do you think that – in theory – they would have similar replication cycles? 8. In your own opinion, do…
I am having a hard time digesting this article https://www.sciencedaily.com/releases/2016/04/160429095038.htm to answer the following questions Summarize the article in 4-6 bullet points. How does this article relate to the information you've read/watched in Module 2? Discuss in detail /reflect on info from textbook, articles, videos about our immune system and our gut microbes. Does your chosen autoimmunity article involve the innate immune system or the adaptive immune system? or both?- Explain.
When choosing a "first line" drug to treat an infection, the most important characteristic would be? the specific mechanism of action bactericidal broad spectrum low toxicity (fewest side effects) In what cell type can both transcription and translation occur simultaneously? both prokaryotic and eukaryotic cells neither prokaryotic and eukaryotic cells prokaryotic cells eukaryotic cells
Viruses can easily mutate exchange genetic material, mechanisms referred to as antigenic drift and antigenic shift. These changes allow the virus to evade the immune system defenses. Match each term with the correct definition Antigenic drift [ Choose ] [Choose ] Different strains of a virus or strain of different viruses, combine and form a new strain that now has a mixture of the surface antigens Antigenic shift The virus changes genetically by accumulating mutations within the genes that code for antibody-binding sites
You are a visiting nurse assigned to check on Mr. Green, a widower who lives by himself in a two-story house. Mr. Green is a 66-year-old man who has been an uncontrolled diabetic for the past 15 years. His wife used to provide nutritious meals and help him test his blood sugar levels, as well as observe his skin for any lesions. Since she passed away of cancer 1 year ago, he has been isolated at home and is having trouble taking care of himself. His physician initiated the visiting nurse referral after he missed two appointments. He is alert and oriented but appears depressed to you. He reports that he had a callous on his left heel that was thick and bothersome, so he tried to break it down with a callous file, but it began bleeding about 3 weeks ago. Mr. Green states, “It is hard for me to really check my skin because my eyesight is so poor.” He states that it is hard for him to walk anywhere because he has mild discomfort walking on the left foot. He also states, “My groin is itchy…
